XLS Library Technical Service Manual
The library assembly that includes the gripper assembly. The handler
moves side to side on the X-axis, up and down on the Y-axis, and in and out
on the Z-axis. It rotates on the Theta-axis. The handler is referred to as a
medium transport element in the SCSI standard.
Host bus adapter card. A circuit board installed in one of the system
controller's four expansion slots that allows the library to attach to and
communicate with a SCSI bus or Fibre Channel network. The HBAs
supported by the library have two ports, which means you can connect two
networks or SCSI buses to each card.
A library component, such as tape drive assemblies, fans, and power
supplies, that can be replaced without removing system power.
An opening on the front of the library through which cartridges can be
inserted or removed without exposing internal library components.
The beams of invisible, infrared light that extend from the bottom of the
XLS to the top. A detector looks at each beam of light and can detect when
a cartridge is protruding from a slot or when someone has reached into the
library. Also referred to as the light curtain.
Light emitting diode. The library contains five LEDs on its front panel to
indicate its operating status. Additional LEDs are used on each power
supply and tape drive assembly.
A robotic media handler that is capable of storing multiple pieces of
removable media and loading and unloading them from one or more tape
drives in arbitrary order.
The main library module that contains the system controller, touch screen,
status LEDs, controller/power bay, handler, tape drives, I/O ports,
cartridge slots, and optional equipment rack.
The beams of infrared light that extend from the bottom of the XLS to the
top. A detector looks at each beam of light and can detect whether a
cartridge is protruding from a slot or whether someone has reached into
the library. Also referred to as the Inventory Sentry.
One of up to eight partitions of the physical library. Logical libraries
ensure that each software application has dedicated and secure access to
specific tape drives, cartridge slots, and I/O ports. The handler is shared
among all logical libraries.
Library Resource Module. The XLS base cabinet.
Linear Tape Open. An industry standard 1/2-inch tape format also known
as Ultrium.
